WILMINGTON, Mass.--(BUSINESS WIRE)--ONI Medical Systems announces first installations of the new MSK Extreme® 1.5T highfield dedicated musculoskeletal MRI systems at Dartmouth-Hitchcock Medical Center in Lebanon, New Hampshire, and UC Davis Medical Center in Sacramento, California. The performance of the MSK Extreme® 1.5T’s gradient system exceeds that of any clinical MRI today. Its 70 m/Tm gradient strength with slew rate of 200 T/m/s achieves a new level of visualization of articular cartilage and detail resolution resulting in exceptional image quality. “The ONI MSK Extreme® 1.5T delivers images with high spatial resolution of small structures within the hand and wrist which are superior to most whole body MRI systems,” said Douglas W. Goodwin, M.D., Director of Musculoskeletal Radiology, Dartmouth-Hitchcock Medical Center.
